'True Blood' Ryan Kwanten: 'Jason is haunted by his parents' deaths'

The actor revealed that Jason will be consumed by the truth of his parents' murder, claiming that the mystery will affect his very nature.

"It did affect him very profoundly, to the point that it really begins to shift the very fiber of who he is and everything that he thought that he was," Kwanten told The Hollywood Reporter.

"Over the course of five seasons now, he's sort of grown into a caring, soulful guy, and now, with everything crashing before his eyes, he may sort of revert back and be even lower than where he started," he continued.

True Blood star Sam Trammell recently revealed that a lot of people will die at the end of the fifth season of the HBO series.
